我们使用wordpress，woocommerce，woocommerce智能优惠券（大量功能，包括批量导出优惠券功能）和woocommerce自动添加的优惠券pro（添加了bogo功能）
我需要使用复选框从中导入10,000张bogo优惠券 woocommerce自动添加了优惠券专业插件。在我看来，我需要获取id ='_ wjecf_multiply_free_products'以导出到CSV，并在该列中填充“是”
I'm pretty sure I can use this file as a template for integrating a custom field to be exported to CSV, but I'm struggling:
